Fix leak-san false positive

This commit adresses below leaksan find.

I tried to reproduce this locally but 02802_clickhouse_disks_s3_copy.sh
but couldn't. clickhouse-disks did not do anything useful (it would not
even print logging), neither with a standard build nor with a leaksan
build. Could not find further documentation of it or even what this tool
is supposed to do, perhaps it is just for internal use. Also,
- line numbers in the leaksan report were partially missing,
- I am not really sure how Sha256HMACOpenSSLImpl::Calculate is calling
  into hmac_init (there must be some sort of static initialization
  somewhere but I did not find it), and
- my fix is in a weird place due to other restrictions (see the commit
  in the aws-sdk-cpp contrib repo).

The chance that this fix fixes the leak are low.
If it doesn't work, add "# Tag no-asan" + a comment to
02802_clickhouse_disks_s3_copy.sh and don't worry further.

EDIT: The commit fixes the issue, everything is good.
